Abstract
A variety of anomalous properties of compounds can be explained by assuming that the perfect lattices become unstable at low temperatures, but are stabilized by small distortions around point defects which increase with decreasing temperature. In particular, the presence of vacancies explains discrepancies between sound-velocity measurements and recent lattice-constant measurements as a function of pressure.
